Abstract

Selon cette invention, un système de communication et de vérification d'inventaire permet d'effectuer l'interrogation automatique des niveaux de stocks en temps réel et de faire des commandes en temps voulu, ce qui permet de maintenir des niveaux optimaux des stocks. Une unité de stockage, ou trémie, est créée pour chaque article en stock. Un ou plusieurs transducteurs sont associés à chaque unité de stockage pour émettre un signal indiquant le poids des articles en stock renfermés dans l'unité de stockage correspondante. Les signaux sont transmis à des intervalles réguliers à un serveur d'inventaire central qui conserve les informations sur l'emplacement du transducteur et de l'article correspondant en stock telles que celles relatives au poids et au fournisseur. Une logique d'inventaire faisant partie du serveur d'inventaire central calcule la quantité de chaque article en stock sur la base des signaux du transducteur et du poids des articles en stock. La logique d'inventaire comprend également des valeurs de seuil pour les quantités minimale et maximale de chaque article en stock. Lorsque la quantité d'un article en stock atteint un seuil minimal, la logique d'inventaire envoie une commande afin de ramener la quantité des articles en stock à un seuil maximal.
